I applied for this job through Cisco's external website. As a former Cisco employee I found it easy to get phone screens, interviews, and job offers with multiple groups. When I showed up at the interview it was almost as if they had already decided to hire me. I met the hiring manager, who talked about the position at length. We spent most of the time discussing my background and interests and also went for a lab tour. I also met a tech lead and another manager but it was more of a conversation than an interview. Also met the director (see below).

Total Interview process took 3 rounds. One phone screen with basic c coding and os questions. Then one c programming interview on phone. then 6 video interviews focusing on os, comp arch, assembly language, algorithms and projects based on resume and got an offer in a week.
